The Gridded Sedgewick Rafter is now available! A simple design of surprising accuracy commonly used for counting larger plankton. Recommended for its ease of use and reproducible data. Intended for use with either a standard or inverted compound microscope at low magnifications, it limits magnification to about 200 x, which makes it unsuited to examining nannoplankton.
Specifications:
• Frame: brass, mounted on 1" x 3" glass slide.

Palmer Counting Cells, SS, 0.1mL
Similar to the Sedgewick Rafter but specifically intended for nannoplankton. The shallow depth of the circular chamber permits use of 40 to 45 x objectives. Because its magnification limit is 400 to 450 x, it is recommended for 43 x dry objectives of approximately 0.65 n.a. and 4 mm e.f. Do not use unless your sample contains a dense population of 10 or more plankters per field, due to the cell’s small...
